Hello jrech,I’ve been using the KRK KNS 8400 Headphone monitors for a couple of years now and switch between those and my rockit6 monitors when mixing down my tracks.
I find these headphones to be fairly well balanced neutral with very wide dynamic range -( revealing ) hope this helps.

Wouldn’t mix without my Sony MDR-7506’s. They might be a little bright for some people but the are accurate and let me hear everything with clarity. But we always have to find what works best for us.

Absolutely. Sony MDR-7506's are like the Yamaha NS-10's of headphones. The old studio standard Yamaha NS-10 monitors are going to reveal exactly how your mix sounds, good & bad. No exaggerated bass or hyped highs.

Sony MDR-7506's are extremely similar in that respect for headphones. They translate what is going on in a mix, they're very honest and at $100 are really essential in my view. I use different headphones occasionally but _always_ either completely mix on 7506's or at least test mixes with them.

Whatever brand you choose, you will get better results if you use closed back, over the ear headphones, but openback, on the ear can work too. I've used Bose IE2's, which are earbuds/in ear monitor type 'headphones' and they were actually quite useful and a good compliment to my 7506's. The key in using those types to mix with is that they must not be overly hyped with expanded bass or noise reduction gimmicks.

Whichever headphones used to mix it's always prudent to test mixes on monitors to get another perspective and ensure compatibility.
